I never understood this view that 'elite' QBs win titles no matter what. David Carr was touted as a Manning or Luck level talent with phenomenal upside, but the guy was sacked 76 times when thrown into the fire as a rookie, and was never the same (Brady's ability to "feel the pressure" last year was tested at the beginning of the season, and he did take hits and sacks when the line play was atrocious at the beginning of the season - he was not a rookie) and over 6 years of 3-5 sacks per game the guy was broken (Bulger took over from Warner, and broke in two years of that). Any view of Brady behind that Texans line flinging missiles when he never had a chance to develop is ludicrous. Any thought that the poorly designed Texans team would be winning titles with Brady in those years because it had Brady is similarly absurd. It is a team sport. Teams have a hard time winning titles without a great QB, but they have. Great QBs in the Hall of Fame haven't won titles, yet somehow found their way to Canton.
The Cowboys are afflicted with Jerry Jones the GM, who never tried to build a team. Like Al Davis, he wanted the flashy players, often viewed as the colossal busts, who would bring in ticket sales rather than wins. The fantasy football world loves these divas for the stats, and hate it when the Pats bring in guys like LaFell, who aren't rock stars, but forget that is how teams actually win games - with a complete roster. Romo has been snake-bitten (everyone remembers the hold, and 4th quarter interceptions), but the guy has had to throw behind horrible lines and for teams that had no defense for years. He kept them in games that should have been blowouts, and some of those interceptions were because he had to throw without a running game (because there was no offensive line). The Boys finally gave him an offensive line, and he looked very good last year.
Romo statistically is very strong in the 4th quarter, when it matters.
These stats are done by year, so I have no desire to do a comparative analysis of every QB in the NFL (I saw an article saying he has the highest QBR in the 4th quarter with stats since 2006). Would I trade him for Brady? Not on your life. Is he very good at what he does? Yes.
Brady was at least drafted. This guy was undrafted from a smaller school. Not bad, given the path to get to the NFL.
